A Very Rare and Precious Wese' Wound in Thio County
 in Largo ouansistoo.

 in Large Quantities. One of the rarest and most precious metals known to mettallugry, is vana' dium, which is quoted at $66O per ounce or the enormous sum of $lO,OOO per pound. Among the other precious metals found in this county, vAnsdium has also been found in large quantities by Dr. Lincoln on a claim in Big Bug district, on which he has . shaft down fifty feet. Assays from it give a silver value of about $7O per ton. It contained another mineral however, which was pronounced by parties who examined it, as worthless. A short time ago Sidney Cook, the young assayer, who is in charge of Pro lessor Williams office, was shown \ specimen of the ore, and he told the Doctor it resembled vanadium. He made a test of the ore and found his view was correct. Prof. Williams, Prof. Blake and Son all made tests of the ore afterwards and confirmed MT. Cooks assay. The discovery soon spread among mining men, and on application Dr. Lincoln recently sent samples to Europe. There is a ten foot vein of it, carrying a very large per centage. A quantity Of the ore has been left lying on the dump of the mine for years, and a short time since an eastern mining expert visited the place, and quietly sacked up lot of it, remarking to gentleman as he did so. that he would more than make the expenses of his trip out of those sacks
 metal first recognized as distinct in 1901 by Del Rio, who found it in the brown lead ore (now known as vansdi- ni,e) of Zimapan, in Mexico, and called it erythronium. But it was generally considered by chemists, to be chromium. In lS3O Sefstrom found the iron made from the magnetic ore of Taberg, in Sweden, to contain 8 peculiar metal, which he called van sdium, from Vanadis, one of the names of the Scandinavian Goddess Freyla; !; Wohler afterwards discovered the Zimapan lead ore to have the same metal.
 The minerals containing this metal are as follows:
 Dechenite, vanadate of lead and zinc; occurs massive, sometimes with traces of columnar structure. Color, fine deep red to yellowish red and brownish red, also a leather yellow, lustre of fresh fracture greasy.
 Descloizite, 8 vanadate of lead, with iron, copper, zinc and manganese, asim- purities, orthorhombic, lustre bright. Color black to olive-brown, smallestcrys- tals olive-green with chatoyant bronze lustre.
 Vanadinite, a vanadate and chlo- ride of lead, hexagonal, usually in implanted globule or incrustatiOns, lustre of surface of fracture resinons. Color, light brownish-yellow, straw-yel- low, reddish-brown. Brittle.
 volborthite, vanadate of copper, heIa- gonal, in small six-sided tables often aggregate in globular forms, lustre, pearly to vitreous. Color, olive-green, citron-yellow.
 Also there are vanadates of copper and lime, and containing other metals, not entirely determined.
 The vanadates occur in the Ural mountains, Germany, Sweden, British Isles, Mexico and United States, at the wheatley mine, Phenixville, Penn, where it is found in several combinations. Colorado and Arizona, too, have pro duced the minerals. Prof. F. H. Blake has described the vandinite discovered at the "Black Prince" mine, Pioneer dis trict, Final county, Ariz., where 1t ap- pears in brilliant red and yellow hexag, onal crystals, sometimes red at one eud and yellow to orange and red at the other.
 At the Agua Fria, No. 2 mine, Big Bug distaict, owned by Dr. 0. Lincoln the vandimite occurs in hexagonsl prisms, both simple and those terminst' ing in pyramidal planes. Of resinous lustre and of a reddish-brown color that varies but slightly. Incrusting the sur face and cavities of the ore with masses of crystals of length, reaching three l eights of an inch and 8 quarter inch n diameter, striated vertically. Free o arsenic, copper and other impurities except chlorine, as far ss few blow pipe and acid tests discover.
